[0027] Referring to Figure 1 (a), Figure 1 (b), Figure 2 (a) and Figure 2 (b), the embodiments of the present application provide a device for preventing false triggering of an air flow switch, comprising a cigarette rod 1 and an air flow switch power supply circuit.
[0028] In the embodiments of the present application, the cigarette rod 1 comprises a base body 11, a receiving cavity 12 formed by extending upward from the base body 11, an air flow switch 13, a first power supply electrode 14 of the air flow switch 13, and a second power supply electrode 15 of the air flow switch 13; wherein the receiving cavity 12 is used to accommodate an atomizer W, the base body 11 is provided with a circuit board 16, a battery core 17, and the air flow switch 13, the air flow switch 13, the first power supply electrode 14, and the second power supply electrode 15 are installed on the circuit board 16, the battery core 17 is connected to the circuit board 16, and is used to supply power to electronic components installed on the circuit board 16, for example, to supply power to the first power supply electrode 14 and the second power supply electrode 15, so that the first power supply electrode 14 and the second power supply electrode 15 are used to supply power to the air flow switch 13.
[0029] In the embodiments of the present application, the air flow switch power supply circuit is used to disconnect the connection of the first power supply electrode 14 and the second power supply electrode 15 when the atomizer W is in a pulled-out state, so as to disconnect the power supply of the air flow switch 13, thereby avoiding the generation of false triggering and false reporting when the atomizer W is pulled out.
[0030] Meanwhile, the airflow switch power supply circuit includes a switch circuit arranged on the conductive body of the atomizer W or arranged on the cigarette rod 1, which is flexible in design and strong in adaptability, and can be set differently based on different requirements.
[0031] Referring to Figure 1 (a), Figure 1 (b), Figure 2 (a) and Figure 2 (b), in an embodiment, the airflow switch power supply circuit is a conductive body, which includes a first contact portion 21 and a second contact portion 22, and the first contact portion 21 is electrically connected to the second contact portion 22, wherein one end of the first power supply electrode 14 and one end of the second power supply electrode 15 are located in the receiving cavity 12. When the atomizer W is in the non-pulled-out state, the first contact portion 21 is electrically connected to the first power supply electrode 14 and the second contact portion 22 is electrically connected to the second power supply electrode 15, forming a power supply loop to supply power to the airflow switch 13 through the battery 17; when the atomizer W is in the pulled-out state, the first contact portion 21 is disconnected from the first power supply electrode 14 and the second contact portion 22 is disconnected from the second power supply electrode 15, so that the closed power supply loop cannot be formed with the battery 17, thereby stopping the power supply to the airflow switch 13.
[0032] Referring to Figure 1 (a), Figure 1 (b), in an embodiment, the conductive body is a conductive material layer added to the atomizer W, i.e., the first contact portion 21 and the second contact portion 22 are located on the conductive material layer. When the atomizer W is in the non-pulled-out state, the conductive body is electrically connected to the first power supply electrode 14 and the second power supply electrode 15 to form a power supply loop to supply power to the airflow switch 13 through the battery 17, while when the atomizer W is in the pulled-out state, the first power supply electrode 14 and the second power supply electrode 15 cannot form a power supply loop without the conductive material layer as a connecting bridge, thereby stopping the power supply to the airflow switch 13. Alternatively, the conductive material layer includes but is not limited to a metal material layer such as copper, iron, aluminum, tin, stainless steel, various alloys, or a carbon film, without specific limitation. By additionally adding the conductive material layer, the structure of the atomizer W can be changed as little as possible, for example, when the non-conductive material is used to manufacture the shell of the atomizer W, the original structure of the atomizer W does not need to be changed, thereby saving costs.
[0033] Referring to Figure 2 (a), Figure 2(b), in one embodiment, the electrically conductive body is part of an electrically conductive housing of the atomizer W, when the housing of the atomizer W is an electrically conductive housing, the electrically conductive housing of the atomizer W can be directly used as the connection medium of the first power supply electrode 14 and the second power supply electrode 15, and the first contact portion 21 and the second contact portion 22 are located on the electrically conductive housing. Specifically, when the atomizer W is in the non-extracted state, the electrically conductive body electrically connects the first power supply electrode 14 and the second power supply electrode 15 to form a power supply loop, that is, the first power supply electrode 14 and the second power supply electrode 15 are electrically connected through the electrically conductive housing, so that the airflow switch 13 is powered by the battery 17; when the atomizer W is in the extracted state, the first power supply electrode 14 and the second power supply electrode 15 cannot form a power supply loop because there is no electrically conductive housing as a connection bridge, and the power supply to the airflow switch 13 is stopped.
[0034] Referring to Figure 3 (a), Figure 3 (b), in one embodiment, the switch circuit includes a micro switch 23, the moving contact of the micro switch 23 is electrically connected with the first power supply electrode 14, the stationary contact of the micro switch 23 is electrically connected with the second power supply electrode 15, and the atomizer W is used to apply a force to the action spring of the micro switch 23. Specifically, when the atomizer W is in the non-extracted state, the atomizer W presses the action spring of the micro switch 23, the moving contact of the micro switch 23 is electrically connected with the stationary contact of the micro switch 23, so that the first power supply electrode 14 and the second power supply electrode 15 are electrically connected to form a power supply loop, and the airflow switch 13 is powered by the battery 17. When the atomizer W is extracted from the micro switch 23, the action spring of the micro switch 23 is subjected to a counterforce, the moving contact of the micro switch 23 is disconnected from the stationary contact of the micro switch 23, the first power supply electrode 14 is disconnected from the second power supply electrode 15, and the power supply to the airflow switch 13 is stopped.
[0035] In one embodiment, the switch circuit includes an MCU (not shown), a proximity sensor (not shown), and an electronic switch, the MCU is connected with the proximity sensor and the electronic switch, the electronic switch is connected with the first power supply electrode 14 and the second power supply electrode 15, and the proximity sensor is used to sense the atomizer W. Specifically, when the atomizer W is in the non-extracted state, the proximity sensor senses the atomizer W, the MCU controls the electronic switch to be in the conductive state, the first power supply electrode 14 and the second power supply electrode 15 are electrically connected to form a loop, and the airflow switch 13 is powered by the battery 17; when the atomizer W is in the extracted state, the proximity sensor cannot sense the atomizer W, the MCU controls the electronic switch to be in the non-conductive state, the first power supply electrode 14 is disconnected from the second power supply electrode 15, and the airflow switch 13 cannot be powered.
[0036] Optionally, the proximity sensor includes, but is not limited to, an infrared, inductive, capacitive proximity sensor or a Hall sensor; the electronic switch includes one of a triode, a field effect tube and a photoelectric coupler, and the control principle of the triode, the field effect tube and the photoelectric coupler is the same, that is, when the atomizer W is pulled out, the proximity sensor cannot sense the atomizer W, the MCU is informed, and the MCU controls the triode, the field effect tube and the photoelectric coupler to be in an off state. The following is described by taking the triode as an example:
[0037] As shown in Figure 4 VCC is provided by the battery core 17, when the atomizer W is in the pulled-out state, the proximity sensor cannot sense the atomizer W at this time, the MCU sends a control signal at this time, the base of the triode is reached through the resistor R1 at this time, the triode is in a cut-off state, so that the first power supply electrode 14 and the second power supply electrode 15 are disconnected, and the airflow switch 13 cannot be powered.
[0038] In the embodiment of the application, an electronic cigarette is also provided, which includes the atomizer W and the above-mentioned device for preventing the airflow switch from being triggered by mistake.
